GENERAL INFORMATION ABOUT
THE APPLICATION TECHNIQUE
7.1

SPRAYING TECHNIQUE

While spraying hold the spray gun at a uniform distance of 30
– 60 cm from the object. Otherwise the spray pattern will be
uneven.
The spray pattern depends on the coating material, the viscos-
ity, the nozzle size and the working pressure.
Test the desired texture on a test surface.
The lateral limit of the spray jet should not be too sharp. The
distance between the spray gun and the object should there-
fore be selected correspondingly.
The spray edge should be gradual in order to facilitate over-
lapping of the next coat.
If the spray gun is moved parallel and at an angle of 90° to the
surface to be coated, the paint mist is minimized.
Note:
Grains and pigments with a sharp edge result in a high rate of
wear of the pump, high presure hose, speay gun and tip.
When using the high pressure hose while
working on scaffolding, it is best to always
guide the hose along the outside of the scaf-
folding.

SHUTTING DOWN AND CLEANING

Do not clean the motor and control unit of
the machine moistly. And certainly do not
spray down the unit with high-pressure
cleaners or high-pressure steam cleaners.
Danger of short-circuits caused by water
ingressing.
• Pump the container until it is as empty as possible, but do
not let it run dry.
• Switch the machine off and secure the trigger guard.
• Remove and clean the nozzle and nozzle holder from the
spray gun.
• Put water in the container and hold the spray gun over
an empty bucket.
Important: Do not let the mortar spraying machine run
dry. During the cleaning process, ensure that there is al-
ways enough water in the container.
Important: Do not let the machine run
dry. If an empty container is not topped
up within around 2 minutes, the pump
switches itself off and must be restarted
once the material is topped up.
• Set the pressure regulator to the yellow area (stage 1-4).
• Un-secure and pull the trigger guard on the spray gun.

GENERAL INFORMATION ABOUT THE APPLICATION TECHNIQUE

• Pump material out of hose into container until the material
exiting the hose is just a thin liquid.
• Release the trigger guard and secure it.
• Set selector switch to "0".
The high pressure hose must be pressure-
less.
If necessary, set the selector switch briefly
to "R" (reverse).
Watch the manometer ––> 0 bar.
Wear safety goggles.
• Decouple high pressure hose from pump unit.
• Decouple spray gun from high pressure hose.
• Insert cleaning ball into high pressure hose and reconnect
high pressure hose
• Set selector switch to "F".
• After a few seconds, the cleaning ball exits the high-pres-
sure hose.
• Depending on the processed coating material, repeat the
cleaning process 3 – 4 times.
• Set selector switch to "0".
• Decouple high pressure hose from pump unit.
• Clean the outlet unit with a jet of water and a suitable bottle
brush.
• Clean the container with a jet of water and a suitable brush.
• Clean the protective grid with a radiator brush.
In the event of interruptions / storage, the
pump unit must always be filled with conser-
vation agent. Otherwise the stator may stick
to the rotor and damage the pump. In the
event of interruptions or prolonged periods
of storage, use PlastGuard longlasting (Art.
No. 2399 960, undiluted).
• Seal the hose connection with the sealing cap.
• Pour 5 litres of suitable conservation agent into the con-
tainer and briefly switch the pump on (the rotor and stator
must be fully covered).
• Clean the spray gun in accordance with the instructions in
the spray gun manual.
